Post-furnace argon blowing detection system

The system mainly includes a gas control cabinet, an electrical junction box, and a display alarm system. This device can realize argon gas flow control, pressure regulation, and local HMI control, remote HMI control, and on-site manual control; as well as real-time monitoring of pressure and flow rate. It provides a standard 485 communication interface and reserves a 4-20ma channel for communication with the host computer.

  • I. Product Overview

    The system mainly includes a gas control cabinet, an electrical junction box, and a display alarm system. This device can realize argon gas flow control, pressure regulation, local HMI control, remote HMI control, and on-site manual control; as well as real-time monitoring of pressure and flow, providing a standard 485 communication interface and reserving a 4-20ma channel for communication with the host computer.

    II. Product Composition

    1. Gas Control Cabinet:

    The gas control cabinet includes: 1 main valve, 1 pressure reducing valve, 1 filter pressure reducing valve, 6 other manual valves, gas pipelines, 2 pressure sensor transmitters; and 2 sets of mass flow controllers. It can set the flow rate value, output the flow rate value, and automatically adjust the flow rate to the set value.

    2. Electrical Junction Box:

    Fixed to the side of the gas control cabinet, it contains all electrical wiring and signal reservation channels.

    3. Display Alarm System:

    Includes 2 displays, 1 LED signboard, and 1 audible and visual alarm. The two displays are the master and slave stations, respectively, and can display pressure and flow signals, as well as various signal trend charts and the communication status of various devices, and can control the mass flow controller. The LED signboard can also monitor real-time flow and pressure. When the flow and pressure signals exceed the user-set limits, the alarm is triggered.
